5.2.1
ABT (Abort) Switch
The ABT switch, located on the CPU board front panel, provides the operator with the ability to
directly terminate the boot operation during the boot wait time which is indicated by the “U” LED
blinking. This is the sole purpose of the ABT switch during the NetBootLoader operation.
5.2.2
TERM Serial Interface
The TERM serial port is used to provide direct operator interfacing to the NetBootLoader. As
soon as the CPU board has been initialized this port is activated and the operator may input
commands. During the boot wait time the operator may terminate the boot operation and take
control of the NetBootLoader. Once the boot wait time is exceeded the command interpreter is
deactivated and the operator no longer has access to the NetBootLoader.
The TERM serial interface may either be directly connected to a terminal device or may inter-
face with a terminal emulator.
5.2.3
SER0 Serial Interface
The SER0 serial port is used to provide the NetBootLoader with the ability to access Motorola
S-Records for programming an application to FLASH. No command interpreter is available for
this interface.
5.2.4
Ethernet Interface
The Ethernet interface provides the capability of remotely interfacing with the NetBootLoader.
Prior to using this interface it is necessary to configure the NetBootLoader network settings.
This is accomplished via the TERM interface. Once the network settings have been made, the
remote operator has the same capabilities as with the TERM interface. During the boot wait
time the operator gains control of the NetBootLoader by logging into it via the Ethernet inter-
face. This causes the boot operation to be terminated and gives control to the remote operator.
The Ethernet interface uses the telnet protocol for operator interfacing with the NetBootLoader.
In addition to the operator interface via Ethernet, the NetBootLoader also uses the Ethernet in-
terface for ftp server access.

NetBootLoader Functions
In addition to initializing the CPU board for operation and the loading and starting of applica-
tions, the NetBootLoader provides the following operator monitor and control functions:
•
NetBootLoader control
•
system status monitoring
•
ftp server access
•
FLASH reading and programming operations
•
Motorola S-Record acquisition
These functions are described in detail in the following chapters.
